Possibly the best feature of a baby (or at least Lilli) is that they will do a little jig at whatever you sing, even if you sing it badly and don't know the words. Which pretty much covers my repetoire. Bob makes fun of me because I never know the words to songs, so I just fill in with what I think makes sense, which always inevitably makes the least sense when you compare with the actual lyrics.

Also, the way she says "heYOO" for "hello" when she wakes up in the morning in wants to wake me up is a pretty good feature too. It's always nice to wake up to a bright and cheery "heYOO."
